Well, I saw some videos of Stan Wawrinka training in Arena Armeec in Sofia and he didn't look so confident. I know there is a lot of difference between matches and trainings, but it's obvious he is far away from his form before the knee surgery last year. His performance in Australian Open was extremely bad, but it was expected, because he needs time to find his rhythm of play. I think it's still too early to tell he's back to his best days and he will win against all of the opponents on his way until receiving the title in Sofia.

Even Berankis from Lithuania put him under so much pressure in Melbourne and what to talk about Sandgren who practically outplayed him in every single component.

This will be Stan first match here in Sofia and I don't expect too much by him. I love this guy but in this form and against a player, who is uncomfortable for him I don't think this will be a straight set victory for the Swiss. They have two matches and all of them were played at max sets- 3-set victory for Stan in Casablanca and last year 5-set marathon in Australian Open won by Stan again. Even close to his best form Stan had so much problems in the start of Aus Open last season, what about now.. and Klizan started from the qualifications here and he has played some matches on the central court, winning in the 1st round against Alex Donski from Bulgaria. His performance was really good, especially on his serve. He has good 1st serve and is also left-handed. I think he has everything to make the match really interesting and why not even to win it, not only taking a set.
